HDAC inhibitors of the general formula (I) and (II) and pharmaceutically acceptable salts thereof, as described herein, are useful as inhibitors of histone deacetylases or other deacetylases, and thus are useful for the treatment of various diseases and disorders associated with acetylase/deacetylase activity as described herein (e.g., cancer). In certain embodiments, the compounds of the invention selectively target either a class or isoform of the HDAC family. Another aspect of the invention provides an assay for determining the inhibitory effect of a test compound on an HDAC protein comprising: incubating the HDAC protein with a substrate of general formula (IIIc) in the presence of a test compound; and determining the activity of the HDAC protein.
本文所述通式(I)和(II)的HDAC抑制剂及其药学上可接受的盐类可作为组蛋白去乙酰化酶或其他去乙酰化酶的抑制剂,因此可用于治疗与本文所述乙酰化酶/去乙酰化酶活性相关的各种疾病和失调(如癌症)。在某些实施方案中,本发明的化合物选择性地靶向 HDAC 家族的一类或同工酶。本发明的另一方面提供了一种测定受试化合物对HDAC蛋白的抑制作用的方法,包括:在受试化合物存在下,将HDAC蛋白与通式(IIIc)的底物孵育;测定HDAC蛋白的活性。
